STOP: c000021a (Fatal System Error)
Problem: Blue screen during bootup, after format there is stop error
Problem was caused by bad Fujitsu HDD,
inside HP Compaq nx6310.
Other symptoms were - data error (cyclic redundancy check) while copying data in ERD Commander. Also full format couldn't be completed, it hangs at 2%. Quick format passed ok.
Once new HDD was instead of the bad one, windows installation went fine.
